As defined by the modern neologisms blog, wordbirds, a "mumblenym" is a word you don't know how to pronounce because you've only seen it written, but haven't heard it said. Mumblenyms are especially common in fashion, a niche global industry which attracts talent and fans from all over the world; consequently, the number of pronunciation guides available online currently hovers somewhere near in infinity. There are Vogue slideshows, explainer videos, even mobile apps all dedicated to the topic of how to pronounce fashion designer names. And now, i-D has made its own contribution to the genre with a model-packed A-Z guide.
